Great unit from Meteor! This is the Stargate unit (white version). The unit features a 80 volt, 300 watt discharge lamp to produce pure white beams that project from the front of the unit. The effect comes from a long metal cylinder that wraps around the bulb and rotates. There was also a multi-color version that added dichoric glass pieces in the rotating cylinder but this version just uses the slits in the cylinder for the fast motion the unit produces. The fixture is sound active which means when the music is present the cylinder inside will rotate to the beat of the music this makes a great high energy effect. Very unique and powerful unit. I beleive this unit was sold in Europe under the Prolight brand. Great unit made in China.
